Version 2.15.0

Version 2.15

• Pending API changes:

  • The initialisation of different objects in xtgeo currently manipulates an
    instance of itself. We want to deprecate said behaviour and instead return a
    new instance on each creation. This work have now started, but currently it will
    only produce a warning. In the next major we will deprecate relevant behaviour.

  • The following classes will undergo changes: Grid, GridProperty,
    RegularSurface, Points, Polygons, Well and Cube, but at this stage only
    RegularSurface is affected.

  • For example:

    There are currently multiple ways of creating e.g. a RegularSurface in XTGeo:

    1. Creating an instance and then populating it by reading a file:

    surf = RegularSurface()
surf.from_file('myfile.gri')

    2. Providing a file (any supported file format can be given):

    surf = RegularSurface('myfile.gri')

    3. Using one of the wrapper functions (similarly with cube, roxar, grid):

    surf = xtgeo.surface_from_file('myfile.gri')

    These methods are consistent for all classes in XTGeo.

    Methods 1 and 2 will be deprecated, while using the wrapper function (3) will
    be the preferred approach.

  • Until version 2.14, creating an empty RegularSurface provided a default
    surface with ncol=5, nrow=3, xinc=25, yinc=25 and the following values:
    [[1, 6, 11], [2, 7, 12], [3, 8, 1e33], [4, 9, 14], [5, 10, 15]].
    Creating an empty RegularSurface in this version will still provide the default
    structure, but in version 3 values will be set to 0 instead.
    Creating an empty RegularSurface will however display a deprecation warning, and
    warns that xinc, yinc, ncol and nrow should be set explicitly.

• New features:

  • Python 3.9 support, with PYPI wheel.
  • Add the possibility to write Well to Roxar API #528
  • Read and write ROFF on ASCII now supported #549
  • Add warning for roxar grid with dual index #495 #491 #306

• Improvements and bug fixes:

  • GRDECL file format reading now handles repeat counts. #435
  • Read and write of ROFF files have been refactored and moved to separate
    package (roffio). Speed is improved, and ASCII roff is now supported.
    This solved several bugs and issues related to roff reading, such as handling
    large file sizes and long keywords. #549 #548 #537 #536
  • Fix: Reading a discrete property from file and save in Roxar API is
    now corrected #531.
  • Fix: handling of file extensions with multiple "." in name #592
  • Fix: MAPAXES being ignored when last in file in Eclipse formats #581
  • Fix: handling of subgrids in hybrid grids #553
  • Several cases of non-recoverable exit have now been replaced by an
    Exception #552 #545
  • Fix: a memory access violation issue in translate_coordinates for 3D grids #550
  • Fix: invalid read in surf_get_z_from_ij (C backend) #551
  • Fix: Segfaulting when using get_value_from_xy (C backend) #496
  • Fix: Checks on indices in set_grid in roxar api #578
  • Change datatype for counters, related to #537
  • Fix: Check validity on colnames when setting dataframe for Polygons #506
  • Fix: GridProperty accepts arbitrary line and keyword length when reading GRDECL #504
  • Fix: GridProperty would not accept cases with inactive cells when
    reading GRDECL (introduced in XTGeo 2.6-2.10) #507
  • Fix: Write to roxapi discrete prop #531
